Gaynor quits Katter Party

Former Queensland Senate candidate Bernard Gaynor has resigned from Katter's Australian Party.

Mr Gaynor announced the news on Twitter, saying he'd quit because the party "failed to oppose abortion".

"I have today resigned from Katter's Australian Party because its leadership has failed to live up to the values of the party," he added in a statement.

The KAP doesn't take a position on abortion, believing it's a matter of conscience for individual party members.

Asked for his personal view on the issue on Tuesday, party leader and Queensland independent MP Bob Katter did not give a direct answer and accused journalists of trying to paint KAP as an "extremist organisation".

Abortion has been thrust into the federal election campaign spotlight by Victorian Democratic Labor Party (DLP) Senator John Madigan.

In a speech to the Sydney Institute on Tuesday, Senator Madigan criticised politicians who did not disclose their views about abortion and those whom he accused of not backing their principles with legislation.

Mr Gaynor had sent a number of tweets after sections of Senator Madigan's speech were leaked to media outlets urging politicians - including Mr Katter - to reveal their views.

The Iraq war veteran and father of five was named as one of KAP's Senate candidates last year.

His candidacy was suspended in January 2013 after he said he would not allow gay teachers to educate his children.
